I would recommend posting your payroll checks to a dummy bank account. Then make a general journal entry or a payment from the real cash account to the dummy account using the funds withdrawal date. It adds an extra step but it allows you to reconcile the bank account easily but still leaves your payroll expenses in the correct period.

Create a General Journal entry.   Debit wages and credit the bank account.   Check the box at the top that says reverse transaction.  This will allow you to reconcile the account in July and when the checks come in in August you will be able to reconcile that also.
